Data Code for the study Crop mixtures: does niche complementarity hold for belowground resources? an experimental test using rice genotypic pairs Data: Rice_traits.csv: this file contains trait and productivity data measured at the individual plant level. It has one row per plant and one column per trait. Column headers: IDplant: unique plant identifier (1 to 200) IDpot: pot identifier with two plants per pot (1 to 100) Bloc: bloc identifier, with 20 pots per bloc (A, B, C, D, E) Treatment: P0 vs P+ = no P supply vs P supply Asso: pot type, either monoculture (M) or mixture (P) IDcouple: concatenation of the identifiers of the two genotypes in a pot (I64 = IR64, I64+=IR64 introgressed with QTL9, Pdi=Padi, Ktn=Ketan) IDgeno: focal genotype identifier (I64 = IR64, I64+=IR64 introgressed with QTL9, Pdi=Padi, Ktn=Ketan) IDnei: neighbour genotype identifier (I64 = IR64, I64+=IR64 introgressed with QTL9, Pdi=Padi, Ktn=Ketan) BIOM_above: aboveground biomass (g) Tillers: number of tillers PH: Plant height (cm) Biovolume: biovolume (m3) SLA: Specific Leaf Area (m2/kg) RB_top: Root biomass between 0 and 20 cm below the soil surface(g) RB_deep: Root biomass between 20 and 60 cm below the soil surface(g) (!!! Only measured at the pot-level) D_ad/D_bas: Mean root diameter (mm) of adventitious/basal roots, respectively SRL_ad/SRL_bas: Specific Root Length (m/g) of adventitious/basal roots, respectively RTD_ad/RTD_bas: Root Tissue Density (mg/cm3) of adventitious/basal roots, respectively RBI_ad/RBI_bas: Root Branching Intensity (nb tips/cm) of adventitious/basal roots, respectively PfR_ad/PfR_bas: Proportion of fine roots (diameter 0.1 mm) (%) in adventitious/basal roots, respectively Code: Rice_mixtures_analysis.R: this file contains the main statisticl analysis presented in the study. It uses Rice_traits.csv as an input.
